Specific course objectives

The course aims to provide the cultural background necessary to understand the basic principles of thermodynamics and thermal energy analysis and the basics of heat transfer by conduction, convection and radiation to apply them through exercises to system components and power systems. At the end of the course the student will be able to set the analysis of thermal systems and will have acquired a set of concepts that allow the examination of the practical problems of heat transfer of systems.

Course programme

Thermodynamics - Fundamentals
Principles of thermodynamics: introduction, definitions. Reversibility and irreversibility. Work and heat. Principle I of thermodynamics for open and closed systems, internal energy and enthalpy. Principle II: statements, entropy. Efficiency of thermodynamic cycles. Carnot cycle. COP. Properties of fluids on diagrams. Ideal gases and their major transformations. Ideal gas cycles (outline): Otto, Diesel and Joule. Efficiency. Direct and reverse cycles (with phase liquid-vapor) heat pumps.

Heat transfer - Fundamentals
Mechanisms of heat transfer. Heat conduction in solids: Fourier law of conduction and its application to flat and cylindrical surfaces in steady state, thermal insulation ancd critical insulation thickness, electrical analogy. Heat transfer in natural and forced convection, finned surfaces. The overall heat transfer coefficient. Heat transfer by radiation: definitions, fundamental laws, black body, shape factors, electrical analogy. Heat exchangers.

Testing and exams

To access the examination one or more exercises set at the beginning of the course must be prepared. The details of the development and delivery of exercise are defined in the web page of the teacher. The final assessment is a written test and a conversation (normally the day after the written test).
